Thanks to the adoption of blockchain technology, we have seen the increased adoption of the use of cryptocurrency around the globe. This has led people to either mine for it or buy it for sale later on. Thanks to this, there has been a cryptocurrency ‘gold rush’ of sorts and this has led to some using unscrupulous ways of using the CPU power of unsuspecting users.
On September, we started seeing reports of websites like Pirate Bay and some Kenyan ones that contained scripts of a browser based miner called Coin Hive like. This miner harnessed the power of a user’s CPU power when they are browser which is used to generate money for the website if it was done intentionally.
They found two categories of malicious apps on the Play Store that were detected as ANDROIDOS_JSMINER and ANDROIDOS_CPUMINER.
Fortunately, they reached out to Google and these apps are no longer on the Play Store, which is a relief. This means from now on, you will be required to be checking the CPU usage of your phone as a first indication whether you might have a rogue app installed.
It was found that 500 million people were vulnerable to in browser cryptocurrency mining so make sure to be extra vigilant of these attacks. On desktop, you can use such handy Chrome extensions to block cryptominers from taking your laptop, but we now have to wait and see what we can get for our phones.
